0–100, higher is better. How it is calculated

The website naturgas.dk currently returns an HTTP 404 error page indicating that the requested resource is not found. This prevents access to any meaningful content, metadata, or business information on the site. The domain is registered since 1997 with Eurodns S.A and is active, suggesting a legitimate and long-standing presence in the energy sector, specifically related to natural gas in Denmark. However, the lack of accessible content and security features severely limits the ability to assess the company's digital maturity or security posture. From a technical perspective, no modern technologies, frameworks, or CMS platforms are detectable due to the minimal HTML content. There is no evidence of HTTPS enforcement, security headers, or privacy compliance mechanisms such as cookie consent banners or privacy policies. This indicates a poor technical implementation and a high risk from a security and compliance standpoint. Security posture is weak with no visible security best practices implemented. The absence of contact information, incident response channels, or vulnerability disclosure policies further exacerbates the risk profile. The domain registration is consistent with a legitimate business, but the website's current state undermines trust and user confidence. Overall, the website is currently non-functional for end users and lacks critical security and compliance features. Immediate remediation is required to restore website availability, implement HTTPS, add privacy and cookie policies, and provide clear contact and business information to improve trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The domain naturgas.dk is associated with the energy sector in Denmark, likely representing a company involved in natural gas services or infrastructure. The domain age (since 1997) indicates an established entity. However, the lack of accessible website content limits insights into market positioning, competitive advantages, or business model specifics. No partner or subsidiary domains were identified. The absence of digital presence and business information online may hinder customer engagement and market competitiveness. The company should prioritize restoring its web presence and enhancing digital communication channels to support growth and customer trust.

Security posture

The current security posture is poor due to the absence of HTTPS, security headers, and privacy compliance mechanisms. No incident response or vulnerability disclosure information is available. The website's 404 error page and minimal content suggest possible misconfiguration or downtime, which could expose the organization to reputational risk. The lack of DNSSEC and security best practices further weakens the security stance. There is no evidence of secure forms or data protection officer contact details. Overall, the organization should urgently address these gaps to meet GDPR and industry security standards.

Recommendations

  1. Restore website availability and fix HTTP 404 errors to provide accessible content.
  2. Implement HTTPS with a valid SSL certificate and enable DNSSEC for domain security.
  3. Add comprehensive privacy and cookie policies with GDPR compliance indicators.
  4. Publish clear contact information including emails and phone numbers for customer and security incident reporting.
  5. Deploy standard security headers and conduct regular security audits to identify and remediate vulnerabilities.

Technical notes

Notes

The website currently serves only a minimal HTML 404 error page with no metadata, scripts, or structured data. No CMS or frameworks are detectable. The hosting provider is unknown from the data provided. Performance and mobile optimization cannot be assessed due to lack of content. The absence of SEO meta tags and accessibility features indicates technical debt and poor digital maturity. The domain registration is stable and consistent but the website infrastructure requires modernization and proper configuration to support business operations effectively.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
